This helps me understand how a simple FEL mounted plow is all you need!:thumbsup: My drive is not as long as yours is, but if I cleared it like you did, the next blow would fill it in to the height of the snow left on each side of the road.
I used to do all my snow clearing with the FEL and wound up having those snow ridges on each side - I call 'em "windrows". After a couple winters of deep snowbanks forming over my drive, I switched to blowing out my drive areas instead. But since you are expecting your snow to melt quickly, what you're using is perfect. Our load of snow won't be gone till around early April.
